sine
Step-by-step explanation:
Answer:
use the cosine (cos)
Step-by-step explanation:
There are three trig functions:
sin
cos
tan
An easy way to remember which sides go with which function is the saying:
soh - cah - toa
so....breaking down the acronoym
sin refers to opposite over hypotenuse
cos refers to adjacent over hypotenuse
tan refers to opposite over adjacent

Triangle JKL is an equilateral triangle with two of its vertices at points J and K. What are the coordinates of point L? Round to the nearest tenth as needed.
Answer:
The X coordinate is 6, since it's midway between J and K. If you draw a midline from L, and running to the midpoint of the line JK, you make two right angled triangle. The length of the midline would be the square root of the difference of the squares of six and three, which is 5.20, which is the offset of the Y coordinate of L from the Y coordinate of J and K, which is 2. Add 5.20 to 2 to get the Y coordinate of L as 7.20. L is therefore (6,7.20)
Answer:
(6, 7.2)
Step-by-step explanation:
Since it is an equilateral triangle, all of the side length must be equal.
Therefore, we know the lengths JK = 6 and JL = 6. If h is the height of the triangle, the Pythagoras's theorem says
(JK/2)² + h² = JL²
putting in the values of JK and JL gives
(6/2)² + h² = 6²
3² + h² = 6²
subtracting 3^2 from both sides gives
h² = 6² - 3²
h² = 27
Taking the square root of both sides gives
h =
[tex] \sqrt[3]{3} [/tex]
h = 5.2
With the value of h in hand, we can now read off the coordinates of L.
The x coordinates of L is 6 (count the boxes along the x-axis until you are under L or halfway between J and K).
The y-coordinates of L is 2 + h = 2 + 5.2 = 7.2 ( how far above the x-axis the triangle is plus the height of the triangle).

Mark wants to paint a mural. He has 1 1/8 gallons of yellow paint, 1 1/9 gallons of green paint, and 7/8 gallons of blue paint. Mark plans to use 3/4 a gallon of each paint color. How many gallons of paint will he have left after painting the mural? Enter your answer as a simplified fraction.
Answer:
We have 31/36 gallons of paint left after painting the mural.
Step-by-step explanation:
"Mark wants to paint a mural. He has 1 1/8 gallons of yellow paint, 1 1/9 gallons of green paint, and 7/8 gallons of blue paint. Mark plans to use 3/4 a gallon of each paint color. How many gallons of paint will he have left after painting the mural? Enter your answer as a simplified fraction."
==================================================================
First change each number into a improper fraction:
1 1/8 = 9/8
1 1/9 = 10/9
7/8 = 7/8
=================================================================
"If Mark has 9/8 gallons of yellow paint, and he uses 3/4 gallons"
-We have to multiply 3/4 by 2/2 to make the denominators same.
3/4 × 2/2 = 6/8
Now subtract 6/8 from 9/8.
9/8 - 6/8 = 3/8
We will have 3/8 gallons of yellow paint.
==================================================================
"If Mark uses 10/9 gallons of green paint, and he uses 3/4 gallons"
- We have to multiply 10/9 by 4/4, and 3/4 by 9/9, to get a common denominator.
10/9 × 4/4 = 40/36
3/4 × 9/9 = 27/36
Now subtract 27/36 from 40/36
40/36 - 27/36 = 13/36
We will have 13/36 gallons of green paint.
==================================================================
"If Mark uses 7/8 gallons of blue paint, and he uses 3/4 gallons"
-We have to multiply 3/4 by 2/2 to get a common denominator.
3/4 × 2/2 = 6/8
Now subtract 6/8 from 7/8.
7/8 - 6/8 = 1/8
We will have 1/8 gallons of yellow paint.
==================================================================
Now, we will add the leftover amounts of paint to find the answer.
3/8 + 13/36 + 1/8
Add "like terms".
4/8 + 13/36
Simplify 4/8 into 1/2
1/2 + 13/ 36
Multiply 1/2 by 18/18 to get a common denominator.
1/2 × 18/18 = 18/36
Substitute 18/36 as 1/2 in the expression.
18/36 + 13/36 = 31/36
So, We have 31/36 gallons of paint left after painting the mural.
==================================================================

Circle with the center at (2,4) which goes through the point (-1,0). What is the equation of that circle?
Answer:
(x-2)²+(y-4)² = 25
Step-by-step explanation:
Standard equation of a circle is expressed as
(x-a)²+(y-b)² = r²
Center = (a, b)
Radius = r
Get the radius
r² =(0-4)²+(-1-2)²
r² = (-4)²+(-3)²
r² = 16 + 9
r² = 25
Centre = (2, 4)
Substitute into the equation
(x-2)²+(y-4)² = 25
This gives the required equation
1. a line that is parallel to y=3/4x-9 has slope m=___________
Answer:
Hi! The answer to your question is [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
This equation is in y=mx+b or -b which is Slope Intercept form for Graphing basically y is the y intercept and b means slope, you don't have to do anything extra to find the slope when its in Slope Intercept Form all you have to do is look for usually its a fraction but it can also be a number but all you have to look for is the number that comes before b in the equation!
